Electronic tilt coverage

ABSTRACT

A booming cell start distance and recommended electronic tilt is identified by retrieving a list of cells served by a first base station. A plurality of grids is generated from the first base station to a predetermined threshold distance. A plurality of selected grids is identified between an acceptable coverage limit and a threshold distance. An evaluation is made regarding whether the first base station is not the dominant cell in each of the selected grids based. The number of grids where the first base station is not the dominant cell site is determined based on a dominant carrier threshold. A column of grids where the first base station is no longer the dominant cell site is determined based on the dominant carrier threshold. A bad booming distance of the cell is determined based on the distance from the first base station and the determined column of grids.

BACKGROUND

Open Radio Access Network (RAN) is a standard for RAN interfaces that allow interoperability of equipment between vendors. Open RAN networks allow processing of information to manage the network at a central location. Because of unique properties at the base station, deployed radios encounter interference from other radios in the neighborhood.

Radio interference results in sub-optimal network coverage. Often sub-optimal networks require expensive deployment of additional base stations.

In some embodiments, a system determines an electronic tilt based on signal information received and processed in a cloud environment for managing a radio network. For example, the system is able to determine an electronic tilt to change the tilt of a base station radio to correct booming.

In some embodiments, the system is able to use the booming start distance to dynamically manage the open ran network. For example, the system uses the booming start distance information to change the electronic tilt of the radio on the base station to target a location within the cell site where a majority of the users are present. In at least one example, the system uses the booming start distance in real-time to optimize the radio network during transient changes to usage patterns. In at least one example, the system uses the booming start distance in real-time to optimize the radio network instead of deploying additional base stations or radios based on the number of users in a specific location that are experiencing bad network coverage. In at least one example, the system uses the booming start distance information to determine whether deploying additional base stations is more optimal compared to leasing additional network coverage from a partner network.

In an embodiment, a system determines a booming cell start distance and recommended electronic tilt. In some embodiments, the system retrieves a list of cells that are served by a first base station from a site database that includes a predetermined threshold of sufficient geo-located samples that are beyond the good coverage limit. In some embodiments, the system generates a plurality of girds from the first base station to a predetermined threshold distance in the direction of the azimuth of the first base station. In some embodiments, the system identifies a plurality of selected grids that are between the acceptable coverage limit and the predetermined threshold distance from the plurality of grids.

In some embodiments, the system determines a median grid level reference signal received power for cell sites from base stations that are received at each of the plurality of selected gird. In some embodiments, the system evaluates whether the first base station is not the dominant cell in each of the plurality of selected grids based on the average reference signal received power and the median grid level reference signal. In some embodiments, the system determines the number of grids in the plurality of selected grids where the first base station is not the dominant cell site based on a dominant carrier threshold. In some embodiments, the system determines a column of grids where the first base station is no longer the dominant cell site based on the dominant carrier threshold. In some embodiments, the system determines the bad booming distance of the cell based on the distance from the first base station and the determined column of girds. In some embodiments, the system determines a column of grids where the first base station is no longer the dominant cell site based on a booming start threshold.

In some embodiments, the system 100 receives information such as the tilt parameters for electrical tilt. In some embodiments, the system 100 receives data about new cell sites or base stations in the network in the past seven days.

The system 100 is configured to automatically detect cell range for a first base station 230 or a cell site. In some embodiments, the system 100 determines a sector 202 (FIG. 2 ) at a first base station 230. In some embodiments, the system 100 determines the sector 202 (shown in FIG. 2 ) based on the morphology, the longitude, latitude and azimuth of the radio or antenna. In some embodiments, the sector 202 encloses a 210 degree sector with a center at the longitude and latitude of the cell site or a first base station in the direction of the beam of the radio network.

In some embodiments, the system 100 determines a sector 105 degrees to the left and the right side of the azimuth line of the radio or antenna. In some embodiments, the system 100 divides the sector 202 into subsectors 204 a-g. In some embodiments, the system 100 divides the section of 210 degrees into seven subsectors 204 a-g of 30 degrees each. In some embodiments, the number of subsectors is based on the bearing angle and coverage of the radio signals. In some embodiments, the number of subsectors is based on the processing load on the system 100, which increases without a significant improvement in performance of the system 100. If the number of subsectors is too small, the system 100 has difficulty determining a nearest neighbor because of the bearing angle and the width of the coverage of the radio networks in the field. In some embodiments, the system 100 determines the sector size using a maximum search limit threshold. In at least one example, the maximum search limit threshold is 6000 meters. In some embodiments, the maximum search limit threshold is based on manufacturer specifications detailing the range where the equipment provides optimal coverage. In some embodiments, if the maximum search limit threshold is too high the processing load on the system 100 increases without a significant improvement in performance of the system 100. In some embodiments, the system 100 determines a nearest neighbor cell site or base station from the first base station at the center of the sector.

In some embodiments, the system 100 determines the nearest neighbor base station from the first base station 230 for each subsector (204 a-204 g). In some embodiments, the system 100 stores the distance between the first base station 230 and the nearest neighboring cell site or base station.

In some embodiments, the system 100 saves the location of each of the neighboring cells in each of the subsectors 204 a-g. For example, the system 100 saves the latitude, longitude and azimuth for the neighboring cell site or base station found in each of the subsectors 204 a-g. In some embodiments, the system 100 calculates the average distance from the nearest neighboring cell site or base station and the first base station or cell site for each of the subsectors 204 a-g. In some embodiments, the system 100 determines the standard deviation of the average distance for each subsector 204 a-g.

In some embodiments, the system 100 determines whether the nearest neighboring base station or cell site in each subsector 204 a-g is opposite to the first base station 230 or cell site. The system 100 determines the average distance using the average distance of the subsectors 204 a-g with a base station opposite the first base station 230. In some embodiments, the system 100 discards the information such as nearest neighboring cell in the first subsector 204 a and the last subsector 204 g which are not facing the first base station 230 while calculating the average and the standard deviation.

In some embodiments, the system 100 determines a mean distance V based on the average distance in the subsector and the standard deviation of average distance. In some embodiments, the system 100 determines whether the distance of the nearest neighboring cell or the base station is greater than the mean distance V. In response to a determination that the distance of the nearest neighboring cell or the base station is greater than the mean distance v, the system 100 flags the cells as opposing the first base station 230 or cell site. In some embodiments, the system 100 flags the middle three subsectors 204 b-204 f which are closest to the azimuth of the first base station 230 as directly opposite to the first base station 230 or cell site. For example, the system 100 can set a standard deviation flag of 1 to indicate the nearest neighboring base station or cell site is opposite to the first base station 230. In another example, the system 100 can determine a multiplying factor based on whether bearing angle of the nearest neighboring cell site. In at least one example, the system 100 can determine the bearing angle B of the line joining the longitude and latitude of the first base station 230 or cell site and the nearest neighboring cell site. In some embodiments, the system 100 can determine whether the difference between the bearing angle of the first base station 230 or cell site and the nearest neighboring cell site or base station in a subsector is within a range of −30 degrees to +30 degrees. The system 100 can determine the multiplying factor based on the difference between the bearing angles of the radio beam. The multiplying factor can indicate the degree of orthogonality of the neighboring base station or cell site in the subsector and the first base station 230 or cell site. For example, the multiplying factor is 0.7 if the difference in bearing angle is within a range of −30 degrees to +30 degrees. In another example, the multiplying factor is 1.5 when the difference between the bearing angles is outside the range of −30 degrees to +30 degrees.

In some embodiments, the system 100 determines the gain for each subsector. In at least one example, the system 100 determines the gain for subsectors closest to the azimuth of the first base station or cell site is two and the gain for the sectors that are further away from the azimuth of the first base station or cell site is one. In some embodiments, the system 100 determines the cell range for the base station based on the distance of the first base station 230 or cell site from the neighboring base station and the gain of the neighboring base station. For example, the system 100 determines the cell range use the formula, Cell Range=sum (D_i*M_i*G_i*StdDev_i)/sum (G_i*If Neighbor Found (i)*StdDev_i), where D_i is the distance between the first base station and the nearest neighboring base station, M_i is the multiplying factor for the first base station and the nearest neighboring base station M in a subsector, G_i is the gain of the subsector and StdDev_i is the standard deviation flag of the subsector.

In some embodiments, the system 100 sets a default value, such as 11 kilometers if the calculated cell range is zero or infinity. For example, the default value is based on the manufacturer's specifications.

In some embodiments, the system 100 determines whether a cell site in a subsector 204 a-g is a suspected booming site based on the timing advance distribution key performance indicator data. The system 100 retrieves information about on-air cell sites or base stations from the site database. In at least one example, the system 100 determines the count of the continuous gaps in the timing advance distribution key performance indicator data to determine the range beyond a cell site may be booming. In some embodiments, the system 100 determines the booming samples measured during a drive test. In some embodiments, the system 100 determines the booming samples based on data logged in the system 100 from user equipment in the subsectors. In some embodiments, system 100 determines the booming samples that are received beyond the configured count of the continuous gaps. The system 100, determines the percentage of booming samples based on the sum of the booming samples detected after the defined continuous gap and the total number of timing advance distribution samples for a cell. In some embodiments, the system 100 determines whether the percentage of booming samples is greater than a booming sample threshold. In some embodiments, the system 100 discards the cell site if the booming sample threshold is less than the percentage of the booming samples.

In some embodiments, the system 100 excludes on-air cell sites or base stations from the site database to determine the distant suspected cell site. In some embodiments, the system 100 retrieves the timing advance distribution key performance indicator data from the site database. In some embodiments, the system 100 identifies the new acceptable coverage limit or cell range based on the automatic cell range algorithm as disclosed above. In some embodiments, the system 100 can determine whether the booming samples in the timing advance distribution key performance indicator is beyond the calculated cell range. Based on a determination that the booming samples are beyond the calculated cell range, the system 100 can identify the percentage of booming samples based on the sum of booming samples that are beyond the calculated cell range and the total number of timing analysis samples for the cell.

In some embodiments, the system 100 determines whether the percentage of booming samples is greater than a booming sample threshold. The booming sample threshold can be based on historical data. In some embodiments, the system 100 discards the cell site if the booming sample threshold is less than the percentage of the booming samples.

In some embodiments, the system 100 can determine whether a suspected booming cell site needs more information before it is identified as a booming cell site based on the good coverage limit. In some embodiments, the system 100 determines whether to mark a cell as a booming cell based on the good coverage limit such as the manufacturer specification limits. In some embodiments, the system 100 determines whether to mark a cell as a booming cell based on the automated cell range algorithm described above. In some embodiments, the system 100 can retrieve cells identified as suspected booming cell sites from the site database. The system 100 can determine whether the good coverage limit is available. Based on a determination that the good coverage limit value is not available, the system 100 can assign the automated cell range to the cell. The system 100 can determine whether the count of the geo-located samples in a cell is greater than a minimum threshold of samples. Based on a determination, that the count of the geo-located samples in the cell is greater than the minimum threshold of samples, the system 100 can exclude or discard the data on the cell site from further calculation. The system 100 can identify the cell sites or base station where more information is to be collected based on the minimum threshold of samples and the count of the geo-located samples.

In some embodiments, the system 100 generates grids 232 a-n of z meters by z meters (only some grids are highlighted in the figure) from the first base station 230 to a predetermined threshold distance in the direction of the azimuth of the first base station 230. In at least one example, the grids 232 are 50 meter×50 meter grids.

In at least one example, the dominant carrier threshold is a percentage of the average reference power signal and the median grid level reference signal.

In some embodiments, the system, 100 determines a column of grids 214 where the first base station 230 is no longer a dominant cell site based on the dominant carrier threshold. In some embodiments, the system 100 determines the good coverage limit based on the distance from the first base station 230 and the determined column of grids 214. In some embodiments, the system 100 determines whether the average reference signal received power is greater than the median reference signal received power based on a threshold difference parameter indicating the deviation between the values that is acceptable.
